What it argues
Through the story of a new CEO rebuilding a dysfunctional executive team, Lencioni presents a model of five interrelated team failures. Without vulnerability-based trust, teams avoid productive conflict. Without conflict, they never truly commit to decisions. Without commitment, members avoid holding each other accountable. Without accountability, individual status and ego displace collective results. The book closes with practical exercises for each level.
